After reviewing the picture you sent, the design has a common flaw we see with this system.
1. The Valve is a canature, it can easily be replaced with a Clack WS1 or any Fleck other than the 7000 (due to the 32mm-1.05 adapter clearance issues).
2. The tanks appear to be the same size. I will post pictures of our version of this design that we distribute. The GAC tanks diameter is always smaller. This is needed to ensure adequate backwashing of both medias. it should be calculated to within 20% of manufacturers recommendations. On you design, the GAC will be under backwashed, or the resin will be over backwashed. We have discussed this at length with many companies, but the concept seems to difficult to grasp, or they do not like the look of the tanks being different sizes.
I will add more to this later, but I am late for Hockey, back to back games tonight, and 1 of my teams only has 5 players showing up, time for some iron man!
